United States Patent 3,fi85,785 APPARATUS AND HORST MEANS FOR CONSTRUCTIGN Adolphe C. Peterson, 4623 Bruce Ave. 8., Minneapolis 24, Minn. Filed Sept. 19, 1958, Ser. No. 762,084 17 (Iiainis. (Cl. 254--8?) My invention relates to apparatus and hoist means for construction, and it is therefore called Apparatus and Hoist Means for Construction.

The principal objects of my invention are to provide a new apparatus which will render the construction of any types of construction, to which it is adaptable, especially the construction of buildings of a few stories in height, such as two, three, four or five story buildings, more easily accomplished, more efficiently accomplished, more cheaply accomplished, and especially more easily and suitably accomplished with such building material, as concrete, reenforced concrete, or other suitable fire resistant and durable materials. Construction of buildings, such as buildings of a few stories in height, residences, apartment buildings, stores, and other suburban buildings, for commercial, residential or industrial use, has been accomplished with difiiculty, when constructed of concrete or suitable fire resistant materials, and this has resulted in high cost of such buildings, and lack of use, especially of fire resistant materials, as concrete, in such buildings. My object is especially the adaptation of construction so that buildings of a few stories in height may be readily and easily constructed of such materials as concrete, or concrete with metal reenforcement, in an economical manner. While the apparatus is especially adapted to such materials, as fire resistant materials, I contemplate that it is adaptable and useful for construction of buildings of materials such as wood, iron, aluminum, or plastic materials, as well, and with ease of construction, and economy in construction, as compared with presently utilized materials, apparatus, and methods. Especially, an object is such constructions, with such convenience, that the result is less danger in construction, to persons engaged in such construction. In general the object is improvement in apparatus for construction.

The principal devices and combinations of devices, comprising my invention, are as hereinafter described, and as defined more particularly in the claims. In'the accompanying drawings which illustrate my invention, like characters refer to like parts, in so far as practicable. Referring to the drawings:

FIGURES 1, 2, 3, and 6 illustrate an apparatus which is used in my construction method, and of these figures FIGURE 1 is a section vertically through the axial centers of principal elements constituting one of the elevating or lifting means, this section being on the line 1--1 of FIGURE FIGURE 2 is a section of a detail, on the line- 2-2 of FIGURE 1, showing one of two suspension stirrups; FIGURE 3 is a vertical section of a detail, on the line 3-3 of FIGURE 1, showing one of two upward thrust elements which may be designated as wrist-blocks; FIGURE 6 is a diagrammatic detail showing the hydraulic control means as it relates to control of a set of the hydraulic elevator means.

FIGURES 4 and 5 show four of the apparatus shown in FIGURES l, 2, 3, in use with a concrete construction; FIGURE 4 being a view in side elevation looking from one end or away from one end of a construction utilizing four of the apparatus of FIGURES l, 2, 3; FIGURE 5 being a plan view looking from above a construction employing four of the apparatus (FIGURES l, 2, 3), such apparatus being shown in plan view, that is from vertically above'upper ends of the individual apparatus. Only two of the apparatus are visible in FIGURE 4.

3,085,785 Patented Apr. 16, 196 3 Ice FIGURES l, 2, 3, are on the same scale; FIGURE 4 is on a scale approximately two-thirds that of FIGURE 1; FIGURE 5 is on a scale approximately one-fourth that of FIGURE 1.

Referring first to FIGURES l, 2, 3, and also FIGURE 4 which shows an apparatus in use, there is illustrated a so-called elevator unit, which is also in part a holding or retaining unit, this unit has as its base a very strong steel or other metal integrating means 1 and this has, upwardly extending from it, two very strong standards 2 which at their lower ends are welded into the integrating means 1 or otherwise very firmly secured thereto. The standards 2 each have cylinder boresZa formed therein and these are open at their upper ends for insertion of pistons, and are very well finished on their interior surfaces for facility of movement of pistons therein. Each standard 2 is approximately ten to twelve feet in height, this height depending on their prospective use or uses, and each has formed therewith or firmly attached to the upper side thereof holding bracket means 3 these being so located that they are at the same horizontal level. The cylinder bores 2a are approximately as long vertically as the standards 2 wherein they are formed and may be as large as is deemed necessary for a predetermined use of type of construction, and this diameter may he say one foot, more or less, or even much larger, as deemed necessary The standards 2 on one integrating means 1 (one elevator unit), may he say one to two feet apart, as may be deemed necessary for accommodation of other elements. They may be further apart, as may be preferred.

Each cylinder bore 211 has vertically reciprocable in it with a close but slidable fit a piston each designated 4 and each piston 4 has projecting upwardly from it a relatively long piston rod 5, each being say ten to twelve feet long vertically. Each piston rod 5 has placed on its extreme upper end a U-shaped block, which may be otherwise called a wrist-block, each designated as 6, and these are dimensioned as necessary for proper strength and for use, and they are preferably formed of steel. Each wrist-block 6 has a bore 7, formed upwardly from its lower end and has at its upper end depressed into it a U-shaped socket 8. The wrist block-s 6 may be simply placed on top and over the upper extreme ends of the piston rods 5 when in use, or they may be permanently welded thereto or otherwise secured thereto.

The pair of wrist-blocks 6 of the one standard set 2-2 have placed in them, resting downwardly in the U-shaped sockets 8, one hanger pin or transverse bar 9 which is very strongly formed of steel or other material, and this transverse bar has formed integrally with it, one at each end, flanges It), by which the transverse bar is held against endwise or movement axially of it, in the sockets 8-. This transverse bar is merely placed in the sockets 8.

The transverse bar 9 has suspended on it between wristblocks 66 a pair of suspension blocks, each designated 11, each having a socket 12 formed upwardly from its lower end and in which there may be inserted bolts 13, and in its upward end'has formed suspension loops or stirrups 14' by which they are suspended on the hanger pin or transverse bar '9, the loops having larger lower parts 15, so that the transverse bar 9 may easily be insorted in place and without hindrance by the flanges 10. The suspension stirrups 14, have inserted in the pair of sockets 12, the upper two ends of a U-shaped steel or other beam-holder or suspender hanger means 16, which latter has the lower horizontal hoist saddle means 17 and the two upper ends 18', each of which is firmly welded into a socket 112 and also firmly afiixed thereto by the bolts 13, both means of attaching being preferably used,

either being sufficient in some constructions.

The integrating means 1 has formed therein, or otherwise provided, conduit means 19' which will conduct a liquid from a liquid distribution pipe 20 to the lower ends of the cylinder bores 2a, so that liquid may flow thereto, under the associated pistons, from the distribution pipe 20. The distribution pipe 20 distributes liquid, under pressure to as many of the cylinder bores 2a as are included in the elevator units, each of which are denoted E, as are to be used in an elevation operation, four such units being used in the construction, FIGURES 4 and 5. The distribution pipe 20 is connected with a common hydraulic pump 21 (FIGURES 4, 6), which pump is operated when necessary by an electric motor 22 or other motor means. The pump 21 receives liquid supply by way of supply pipe 23, and liquid may be bypassed back to the supply pipe from distribution pipe 20 by means of the by-pass 2'4, and controlled by the hand valve 25. The distribution pipe 20 may be blocked by the hand valve 26, as desired, in use of the apparatus.

The integrating means 1 has bolt holes 27 formed therein and whereby bolts or other means 28 may be used, to be embedded, at their lower ends, in concrete foundations 29, the latter being formed as necessary in any projected construction site, and serving not only for temporary support of the apparatus used for construction, but also for the foundation support for the projected construction.

In the foregoing there has been described one of the elevator units and an associated hydraulic supply means, and it is contemplated that at least two and preferably four or more of such elevator units may be used in unison, in a construction, of a whole or part of a construction.

In the use of my apparatus construction of a projected building may be in parts, that is several constructions forming a construction, or several such parts (as in FIG- URES 4 and in one construction simultaneously formed, or all in one construction, as illustrated in FIG- URES 4 and 5. Such use would depend on the size of the projected construction.

Referring now to FIGURES 4 and 5, especially, for this use, there are shown four of the elevator units, each designated as -E-, and these are placed, two at one end of a construction (or part construction), and two at the opposite end of the construction. Each of the four integrating means of four apparatus is placed on a concrete base 29, poured in the ground site, and the bolts affixing the apparatus unit are placed firmly in place, and the integrating means 1 bolted thereto, the nuts 30 being placed on the bolts. The distribution pipe 20 is connected to the hydraulic pump 21 and the supply of liquid provided (not shown) for the supply pipe of the pump. The ground site is prepared for the first floor or roof element construction, by leveling and forming the ground or a wood, metal, or plastic or other covering for the ground, this being placed to form a mold, the upper surface and sides of which are according to the dotted lines M in FIGURE 4. There will be two deep depressions N in which hoist beam members 31 may be placed and above these forms P for the poured concrete beams of a floor element or unit, and the surfaces P1 for the level floor construction. This mold preparation may be of any type but is not shown, except by the lines M, and it will form, when wet concrete is'poured on it, a molded concrete fioor element or unit. Having so prepared the ground mold or form for the poured floor element, the concrete, wet, is prepared. Hoist beam members 31, which are of very strong steel or metal two in number, are placed in the two depressions N, each as long as the poured concrete element will be, and several feet longer, and these hoist beam members lie there during pouring and setting of the poured concrete. The mold forms as prepared and which rest on the ground site or any suitably formed foundation are prepared for the pouring of concrete by smearing the surfaces on which concrete will lie or contact, with any oil or wax or other substance which will render separation of concrete from the forms more easily done. The two hoist beam members 31 are also so prepared. In this prepared condition, each apparatus unit will be in substantially the position as shown in FIGURE 1, the hoist beam member 31 lying in a depression N (FIGURE 4).

The apparatus and ground site being so prepared, such reenforcing material, as steel rods are placed, for embedding in the poured concrete. Reenforcing material of any kind and form may be used and placed so that it may be incorporated in the concrete floor panel to be formed and the completed panel may have plates 34 and 35 or any other means respectively above and below the floor panel and by which the construction may in its entirety be performed. There will be in a floor section, as shown, four plates 34 and four plates 35.

The concrete is poured in the wet state upon the mold forms as described, and in such floor panel form as may be predetermined and provided and this will set around the reenforcing and will provide in the hardened concrete, the floor panel which is designated as 01 FIG- URE 4, all this forming one floor panel unit, integral as such, and having as a firm part the plates 34 and 35, near each of the four floor corners. The usual time for conrete setting is given, and when past, the entire concrete floor panel with its beams or other reenforcing material, may then be lifted by the four elevator units, and the two hoist beam members 31, which are the hanger beams, and now lie under the concrete, as hardened. The valve 26 is opened, the electric motor 22 is caused to operate and pump liquid, as oil or water, into the distribution conduit 20, and this liquid under pressure starts to fill up all the eight cylinder bores 2a of the four elevator units, and this filling is simultaneous, and applies lifting power to both of the two hoist beam members 31 by upward force of the piston rods 5 against wrist-blocks 6, transverse bars 9 of all the elevator units, and this force is equal in all, so that the concrete floor element, as hardened, is lifted equally at all sides and corners. If there should for any reason be any unequal lifting, this may be corrected by temporarily shutting either valve 40 or 41, the distribution pipe 42 being provided for the elevator units at the opposite end of the construction. The floor panel is lifted approximately eight or nine feet, depending on the projected height between floors, of the construction, and thereupon other or alternative retention or holding beams 43 are placed in position by the work personnel, these latter beams being separate and individual, and each being of strong construction, preferably steel. Each retention beam member 43 is placed under the last constructed floor section on two holding bracket means 3, one at each end of the construction apparatus, and thereupon the by-pass valve 25 is opened for a brief time to allow a little liquid to escape from distribution pipes 20 and 42, so that the floor panel will settle a short distance, say one or two inches, and rest on the four retention beam members 43. When that is accomplished,

the liquid may be permitted to escape from the cylinder bores 2a of the apparatus, at both ends, until the pistons 4, piston rods 5, and the hanger means 16 are lowered to their positions as in FIGURE 1 and hoist beam members 31 again rest in recessions N, these having been prepared again, in the meantime, for another concrete pouring.

There will be as many formations of a horizontal building section such as roof and floor sections as there will be floor sections and roof section in a projected building construction, or floor sections if a roof is to be otherwise constructed. Each such horizontal section as a floor is constructed, as by the placing of new reenforcing means of metal and pouring of concrete thereon or other floor forming substance in lieu of concrete, and it will be formed on the originally prepared mold or ground site, the mold such as may have been used having been left in its original place on the ground site, that is such succeeding floor constructions are formed on the same ground level or close thereto as was the case with the first constructed section, or any previously constructed sections on the site, the previously constructed sections having been hoisted therefrom. For

each such construction of a horizontal building section, the hoist beam members 31 which may otherwise be called lift or hoist beams are placed in the depressions N as before, and these are so prepared orcovered that such hoist beam members 3-1 will not be included within the constructed concrete section but will, during the formation of the section, merely lie thereunder so they will not be attached in the constructed section, but so that the hoist beam members 31 are available for the subsequent hoisting of the constructed section.

Prior to construction or pouring of concrete of a new or succeeding floor section, or at substantially the same time, precast concrete metal reenforced columns (pillars) A (FIGURE 4) each having upper and lower plates 45 and 46 are placed under the lower plates 35 of the floor panel or section which has last previously been constructed and hoisted and is supported by the temporary retention beam members 43 (otherwise called holding beam), the retention beam members 43 being in turn supported on the holding bracket means of two elevator units, and plates 45 and 35 at each column are welded together at all four sides of each associated pair of plates 45 and 35. In lieu of welding, each such pair of plates 45 and 35 is bolted or riveted together near all side edges of the pair of plates. Thus there will then be one column A welded by its upper plate to a lower plate 35 of the last previously formed floor section.

The pouring of concrete upon reenforcing steel or metal, as above described, is now repeated, and a new floor panel cast and hardened, the two hoist beam members 31 having been first placed under the locations,

in recesses N. When this new floor section is cast, complete as before, with hoist beam members and plates this may be lifted a few inches, until contact of its plates 34 is made with the plates 46 at lower ends of the four columns A, which are attached to the first floor panel cast. The plates 46 and 34, the latter of the new floor panel, are now welded or otherwise secured together, and

thereupon the two cast floors, with intermediate columns, are firmly joined together, as a construction, and the liquid may again be pumped under high pressure .into the cylinder bores 2a thus lifting the piston rods v5 and the attached hanger means, and hoist beam members 31, so that the entire construction, as so far made,

lifts as a unit, containing two floor elements, four columns, and it is lifted to a position such that the second cast floor element C2 occupies the same relative position as floor element 01, FIGURE 4, previous.y did, that is, when C2 is cast. The floor element Cl will now be a floor height above that position. And now, another floor element may be similarly cast, and columns placed, and the entire structure, now containing three floor elements, C1, C2, and one not shown, Will be, with the two intermediate sets of columns placed as before described, in one integral structure, and may again be elevated in the same manner as before. The process may be repeated, as many times, with as many formed floor elements, and intermediate columns, as the projected construction will require, and that may be so as to provide two, or three, or four, or five, or six, floors and with intermediate columns.

After the floor and column construction, as described is made, any type of walls, such as curtain panels, containing window and door openings, as such as usually constructed, may be secured to the constructed floor elements and columns, in any manner, and such applications, may be made, as the structure proceeds, or after the concrete structure is completely formed and elevated to its permanent position. The lower-most columns will be secured to the foundation concrete 29, this being then,

.their contemplated movement.

or before, provided with the necessary means, such as plates similar to plates 34, for secure attachment of the lowermost columns.

Each of the cylinder bores 2a in each unit E, at each end of a construction site, is provided with an aperture 4 7, which is otherwise called a release port or means, and by which, when the pistons 4 are elevated to the upper extreme of their projected positions, fluid may be automatically released if the elevation of the pistons 4 of any of the apparatus exceeds the extreme positions which the pistons may occupy, this being determined by the. necessity of preventing such elevation, that vertical support of the pistons 4 and rods 5 is rendered precarious or dangerous. Any other means for this purpose may instead be provided. The pistons 4 should in any case be of such long and strong construction that they are firmly held in the vertical positions, at any location of Any other means may be provided to serve this function or additionally serve this-function of support.

It is contemplated that the floor panels C and C and columns A are in the drawings shown only diagrammatically to represent such panels and columns, and it is further contemplated that such constructionfloorpanels and columns such as C and C and A may be formed of any material and of any suitable form and that, any wood forming or framing or other framing material may be used and the units constructed and united in any manner and to be hoisted and progressively formed and attached in the projected construction as has been described.

The building construction proceeds and is similarly elevated and secured or retained, and it, the frame so constructed, may be covered with flooring of any kind, either before or after elevation of the floor unit or member. And vertical columns may be secured between floor members, as in the first case.

While I have shown particular devices and combinations of devices, in the illustrations, I contemplate that other detailed devices and combinations of devices, especially other forms of the elevator units and motive means in connection, and retention means, may be used in the realization of my invention, without departing from the intent and contemplation thereof.
